SPINNING APPARATUS WITH FlO'I'ATlNG:A HEAD.

SPECIFICATION forming part bf retter abent N0. 724,954., dated April 7, 1903.

f Application filed May 3,1902 Serial No. 105,804. (No model.)

To all whom it mayconcern:

Be it. known that I, JULIUS EMIL SCHMIDT, manufacturer, a subject of the GermanErnperor,of Sohloppenhof, b /Eger C 4, Bohemia, Austria-Hungary, have invented certain new and useful Improvements in Spinning Apparatus with Rotating Head; and I do hereby declare the following to be a full, clear, and exact vdescription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked there on, which form a part of this specification.

The herein-described invention relates to a spinning apparatus in which thadrawlgg.

-Qllsiare.,jonrualedin rthensnal way in a rotating head in order to turn and draw the bers regularly. In the ordinary devices for this purpose the rotation of the drawing-rolls about their own axes is effected by a gear- Wheel, fast on one of the rolls, rolling upon a fixed Worm. In order to vary the rotation speed, the gear-wheel must be changed or the pitch of the Worm (usually consisting of an elastic metal band) must be altered.

In my invention the alteration of the rotation speed of the drawing-rolls is, easily effected by suitable gearingfor instance, by gear-wheels on the aforesaid drawing-rolls, which wheels mesh directly or by an intermediate gear with a rotating toothed ring or crown-wheel. The rotation speed .of the drawing-rolls about their own axes is therefore dependent upon the difference between the rotation speed of the head which bears the rolls and Hthat of the crown-gear. The latter speed or both can by replacing a single wheel be easily varied for the whole machine. In order to be able to bring the rst twist or yarn easily between the two drawing-rolls, one of the latter is journaled in the hinged cover ofthe rotating head. This head has a easefor the double purpose of protecting the operator from injury and of keeping the rolls and wheels free from bers, oil, dre. In the accompanying drawings there is shown such I an arrangement.

- Figure l is a central vertical section between the drawing-rolls; Fig. 2, an end View with thefupper part of the cover omitted; Fig. 3, aside elevation with the casing in section, and Fig. e a vertical lengthwise section through the drawing-rolls.

In the rotating head a, which at its lower part has a grooved pulley c, the two drawing-rolls d and e are journaled, and the roll e is in this example journaled on the hinged cover b to facilitate bringing the rst twist between the rolls.

On the head ct, capable of rotating freely, is journaled the pulley f. The crown-gear g is fast with f or in one piece therewith. With the crown-gearg mesh the two gear-wheels h and k, which are on opposite sides of the head.

The intermediate gear-wheel h meshes with the wheel il, which is fast on the roll d, while the wheel 7i; meshes with the gear Z of the roll e. When the head rotates in the opposite di* rection to the croWn-gearg, the wheels 71, k roll on the latter, so that the rolls d and e are positively driven in opposite directions to each othen but at the same speed. Variation of the speed of the pulley f alters that of the rolls d and e, (about their own axes.) The alteration of the speed of all the pulleys f on the machine can be effected by a simple change of one wheel, by which the relative velocity of the grooved pulleys f and o is altered, so that any incongruity between drawing and twisting speeds by reason of loose driving-cords, dre., is impossible.

Although I have shown the rolls d and e as positively driven by intermeshing gearing, it will be understood that other well-known means for rotating them may be substituted therefor.

To facilitate feeding the rst twist between the drawing-rolls, the roll e'of the example here given is journaled in the hinged cover, so that it can by lifting the cover be raised from the other roll, d, as shown in Fig. 3.

On the head a there is attached, by the screws n. or in other suitable manner, the an nular casing fm, Fig. 4, which extends from the cover h to the pulley f. This casing has incuts 5p, in which lie the arms that bear the cover when the latter is opened.

The rolls and the headgearing are protected by this casing lfrom fibers, oils, dac., and the casing also protects the operator from injury by' the rapidly-rotating head. The casing has the further advantage that it effects a more equal distribution' of weight asl about the axis of the rotating head, aud thus enables quieter running.

I claim as my inventionl. A spinning apparatus comprising a rotating head, rotating drawing-rolls therefor and a cover for the rolls, one of said rolls being secured to said cover, substantially as and for the purpose described.

2. A spinning apparatus comprising a rotating head, drawing-rolls therefor, means to rotate the rolls and a hinged cover carrying one of the drawing-rolls, substantially as and for the purpose described.

3. A spinning apparatus comprising a rotatiug head, drawingfrolls therefor, a crownpeoe on the head and means to drive it, independent means to drive the head, gears on JULIUS EMIL SCHMIDT.
